NAME
Object::Declare - Declare object constructor
SYNOPSIS
use Object::Declare ['MyApp::Column', 'MyApp::Param'];
my $objects = declare {
param 'foo' =>
is immutable,
valid_values are qw( more values );
column 'bar' =>
field1 is 'value',
field2 is 'some_other_value';
};
print $objects->{foo}; # a MyApp::Param object
print $objects->{bar}; # a MyApp::Column object
DESCRIPTION
This module exports one function, "declare", for building named objects
with a declare syntax, similar to how Jifty::DBI::Schema defines its
columns.
Using a flexible import list syntax, one can change exported helper
functions names (*declarator*), words to link labels and values together
(*copula*), and the table of named classes to declare (*mapping*):
use Object::Declare
declarator => 'declare', # this is the default
copula => ['is', 'are'], # this is the default
mapping => {
column => 'MyApp::Column',
param => 'MyApp::Param',
};
After the declarator block finishes execution, all helper functions are
removed from the package. Same-named functions (such as &is and &are)
that existed before the declarator's execution are restored correctly.
